That is probably the saddest thing I have read all day.
The best teachers I ever had were the ones that taught the subject material but from a relatable manner based on their years of experience. Yes, the best teachers I personally had were older.
The first post was that old timers not sharing their experiences was bad which in my mind extrapolates to old timers should all be teachers.
The second post was that acknowledging the fact that teachers no longer teach but instruct based on a preset curriculum arranged to get grades for specific tests higher.
The fuzzy logic in my head might not be clear to me let alone others, but I feel you're trying to make something out of nothing as well.
